This goodenia grows in rocky places on hills in the Northern Territory, Queensland and eastern New South Wales.
Goodenia grandiflora is classified as "Priority One" by the Government of Western Australia Department of Parks and Wildlife, meaning that it is known from only one or a few locations which are potentially at risk, but as of "least concern" in the Northern Territory and Queensland.[7] [8]
